Yeah, this is a problem. I deal with it by trial and error sometimes, but that's OK for me because I always have a stock of various length bottom brackets on hand.
I have also found that even when there is published chainline specs, they can be off.
I have found that with Sturmey Archer hubs at least, with a single chainring type crank, I've always been able to dial in the chainline with a 110 or 113mm bottom bracket by arranging spacers on the hub axle, or flipping dished cogs or switching to flat cogs.
You could flip cogs on a Alfine 11, but you would not be able to do it with the stock cog with the chain guard attached. That one must be mounted dished side in.
